The invention relates to substituted heteroquinoline-3-carboxamides, to pharmaceutical compositions containing these compounds and also to these compounds for use in the treatment and/or prophylaxis of pain and further diseases and/or disorders.

The treatment of pain, in particular of neuropathic pain, is of great importance in medicine. There is a worldwide need for effective pain therapies. The urgent need for action for a target-orientated treatment of chronic and non-chronic states of pain appropriate for the patient, by which is to be understood the successful and satisfactory treatment of pain for the patient, is also documented in the large number of scientific works which have recently been published in the field of applied analgesics and of fundamental research into nociception.

A pathophysiological feature of chronic pain is the overexcitability of neurons. Neuronal excitability is influenced decisively by the activity of K⁺ channels, since these determine decisively the resting membrane potential of the cell and therefore the excitability threshold. Heteromeric K⁺ channels of the molecular subtype KCNQ2/3 (Kv7.2/7.3) are expressed in neurons of various regions of the central (hippocampus, amygdala) and peripheral (dorsal root ganglia) nervous system and regulate the excitability thereof. Activation of KCNQ2/3 K⁺ channels leads to a hyperpolarization of the cell membrane and, accompanying this, to a decrease in the electrical excitability of these neurons. KCNQ2/3-expressing neurons of the dorsal root ganglia are involved in the transmission of nociceptive stimuli from the periphery into the spinal marrow (Passmore et al., J. Neurosci. 2003; 23(18): 7227-36).

It has accordingly been possible to detect an analgesic activity in preclinical neuropathy and inflammatory pain models for the KCNQ2/3 agonist retigabine (Blackburn-Munro and Jensen, Eur J. Pharmacol. 2003; 460(2-3); 109-16; post et al., Naunyn Schmiedebergs Arch Pharmacol 2004; 369(4): 382-390).

The KCNQ2/3 K⁺ channel thus represents a suitable starting point for the treatment of pain; in particular of pain selected from the group consisting of chronic pain, acute pain, neuropathic pain, inflammatory pain, visceral pain and muscular pain (Nielsen et al., Eur J. Pharmacol. 2004; 487(I-3): 93-103), in particular of neuropathic and inflammatory pain.

Moreover, the KCNQ2/3 K⁺ channel is a suitable target for therapy of a large number of further diseases, such as, for example, migraine (US2002/0128277), cognitive diseases (Gribkoff, Expert Opin Ther Targets 2003; 7(6): 737-748), anxiety (Korsgaard et al., J Pharmacol Exp Ther. 2005, 14(1): 282-92), epilepsy (Wickenden et al., Expert Opin Ther Pat 2004; 14(4): 457-469; Gribkoff, Expert Opin Ther Targets 2008, 12(5): 565-81; Miceli et al., Curr Opin Pharmacol 2008, 8(1): 65-74), urinary incontinence (Streng et al., J Urol 2004; 172: 2054-2058), dependency (Hansen et al., Eur J Pharmacol 2007, 570(I-3): 77-88), mania/bipolar disorders (Dencker et al., Epilepsy Behav 2008, 12(1): 49-53) and dystonia-associated dyskinesias (Richter et al., Br J Pharmacol 2006, 149(6): 747-53).

Substituted compounds that have an affinity for the KCNQ2/3 K⁺ channel are e.g. known from the prior art (WO 2008/046582, WO 2010/046108). In particular, certain quinoline-3-carboxamides have been described for KCNQ modulation (WO 2010/102811, WO 2012/025236, WO 2012/025237, WO 2012/025238).

There is a demand for further compounds having comparable or better properties, not only with regard to affinity to KCNQ2/3 K⁺ channels per se (potency, efficacy).

Thus, it may be advantageous to improve the metabolic stability, the solubility in aqueous media or the permeability of the compounds. These factors can have a beneficial effect on oral bioavailability or can alter the PK/PD (pharmacokinetic/pharmacodynamic) profile; this can lead to a more beneficial period of effectiveness, for example. A weak or non-existent interaction with transporter molecules, which are involved in the ingestion and the excretion of pharmaceutical compositions, is also to be regarded as an indication of improved bioavailability and at most low interactions of pharmaceutical compositions. Furthermore, the interactions with the enzymes involved in the decomposition and the excretion of pharmaceutical compositions should also be as low as possible, as such test results also suggest that at most low interactions, or no interactions at all, of pharmaceutical compositions are to be expected.

In addition, it may be advantageous if the compounds show a high selectivity towards other receptors of the KCNQ family (specificity), e.g. towards KCNQ1, KCNQ3/5 or KCNQ4. A high selectivity may have a positive effect on the side effects profile: for example it is known that compounds which (also) have an affinity to KCNQ1 are likely to have a potential for cardial side effects. Therefore, a high selectivity towards KCNQ1 may be desirable. However, it may also be advantageous for the compounds to show a high selectivity towards other receptors. For instance, it may be advantageous for the compounds to show a low affinity for the hERG ion channel or the L-type calcium ion channel (phenylalkylamine-, benzothiazepin-, dihydropyridine-binding site) since these receptors are known to possibly have a potential for cardial side effects. Further, an improved selectivity towards binding to other endogenic proteins (i.e. receptors or enzymes) may result in a better side effects profile and, consequently to an improved tolerance.

It was therefore an object of the invention to provide new compounds having advantages over the compounds of the prior art. These compounds should be suitable in particular as pharmacological active ingredients in pharmaceutical compositions, preferably in pharmaceutical compositions for the treatment and/or prophylaxis of disorders and/or diseases which are mediated, at least in part, by KCNQ2/3 K⁺ channels.

That object is achieved by the subject-matter described hereinbelow.

It has been found, surprisingly, that substituted compounds of the general formula (I) given below are suitable for the treatment of pain. It has also been found, surprisingly, that substituted compounds of the general formula (I) given below also have an excellent affinity for the KCNQ2/3 K⁺ channel and are therefore suitable for the prophylaxis and/or treatment of disorders and/or diseases that are mediated at least in part by KCNQ2/3 K⁺ channels. The substituted compounds thereby act as modulators, i.e. agonists or antagonists, of the KCNQ2/3 K⁺ channel.

In a first aspect, the present invention therefore relates to a compound of general formula (I),

The bonding of the heterocycloaliphatic residue to the general structure of higher order can take place via any desired and possible ring member of the heterocycloaliphatic residue. The heterocycloaliphatic residues can also be fused with further saturated, (partially) unsaturated (hetero)cycloaliphatic or aromatic or heteroaromatic ring systems, that is to say with cycloaliphatic residue, heterocycloaliphatic residue, aryl or heteroaryl, which can themselves be unsubstituted or mono- or poly-substituted.

The aryl can be bonded to the general structure of higher order via any desired and possible ring member of the aryl radical. The aryl radicals can also be fused with further saturated, (partially) unsaturated, (hetero)cycloaliphatic, aromatic or heteroaromatic ring systems, that is to say with cycloaliphatic residue, heterocycloaliphatic residue, aryl or heteroaryl, which can themselves be unsubstituted or mono- or poly-substituted. Examples of fused aryl radicals are benzodioxolanyl and benzodioxanyl. Aryl is preferably selected from the group containing phenyl, 1-naphthyl and 2-naphthyl, each of which can be unsubstituted or mono- or poly-substituted. A particularly preferred aryl is phenyl, unsubstituted or mono- or poly-substituted.

A substituent can itself optionally be mono- or poly-substituted. Polysubstitution can take place with the same or with different substituents.

Preferred substituents of “aliphatic residue”, “aliphatic group”, “heterocycloaliphatic residue” or “cycloaliphatic residue” are selected from the group comprising F, Cl, Br, NH₂, NH(C₁₋₄-aliphatic residue), N(C₁₋₄-aliphatic residue)₂, NH—C(═O)—C₁₋₄aliphatic residue, NH—S(═O)₂—C₁₋₄-aliphatic residue, ═O, OH, OCF₃, O—C₁₋₄-aliphatic residue, O—C(═O)—C₁₋₄-aliphatic residue, S(═O)₂—C₁₋₄-aliphatic residue, S(═O)₂—NH(C₁₋₄-aliphatic residue), S(═O)₂—N(C₁₋₄-aliphatic residue)₂, CN, CF₃, COOH, C₁₋₄-aliphatic residue, C(═O)—C₁₋₄-aliphatic residue, C₃₋₆-cycloaliphatic residue, 3 to 7 membered heterocycloaliphatic residue, C(═O)NH₂, C(═O)—NH(C₁₋₄-aliphatic residue) and C(═O)—N(C₁₋₄-aliphatic residue)₂.

In relation with “aryl” and “heteroaryl”, the term “mono- or poly-substituted” is understood within the scope of this invention as meaning the substitution of one or more hydrogen atoms of the ring system one or more times, for example two, three or four times, in each case independently of one another, by substituents selected from the group comprising

F, Cl, Br, I, NO₂, NH₂,

NH(C₁₋₄-aliphatic residue), N(C₁₋₄-aliphatic residue)₂, NH—C(═O)—C₁₋₄-aliphatic residue, N(C₁₋₄-aliphatic residue)-C(═O)—C₁₋₄-aliphatic residue, NH—S(═O)₂—C₁₋₄-aliphatic residue, N(C₁₋₄aliphatic residue)-S(═O)₂—C₁₋₄-aliphatic residue, OH, OCF₃, O—C₁₋₄-aliphatic residue, O—C(═O)—C₁₋₄-aliphatic residue, SH, SCF₃, S—C₁₋₄-aliphatic residue, S(═O)₂OH, S(═O)₂—C₁₋₄-aliphatic residue, S(═O)₂—O—C₁₋₄-aliphatic residue, S(═O)₂—NH(C₁₋₄-aliphatic residue), S(═O)₂—N(C₁₋₄-aliphatic residue)₂, CN, CF₃, C(═O)H, C(═O)OH, C₁₋₄-aliphatic residue, C(═O)—C₁₋₄-aliphatic residue, C(═O)—O—C₁₋₄-aliphatic residue, C₃₋₆-cycloaliphatic residue, 3 to 7 membered heterocycloaliphatic residue, benzyl, aryl, heteroaryl, C(═O)NH₂, C(═O)—NH(C₁₋₄-aliphatic residue) and C(═O)—N(C₁₋₄-aliphatic residue)₂; on one atom or optionally on different atoms, wherein a substituent can itself optionally be mono- or poly-substituted. Polysubstitution is carried out with the same or with different substituents.

Preferred “aryl” and “heteroaryl” substituents are F; Cl; Br; CF₃; CN; C₁₋₄-aliphatic residue; phenyl; naphthyl; pyridyl; thienyl; furyl; C₃₋₆-cycloaliphatic residue; 3 to 7 membered heterocycloaliphatic residue; C(═O)—C₁₋₄-aliphatic residue; CC₂H; C(═O)—O—C₁₋₄-aliphatic residue; CONH₂; C(═O)—NH(C₁₋₄-aliphatic residue); C(═O)—N(C₁₋₄-aliphatic residue)₂; OH; O—C₁₋₄-aliphatic residue; OCF₃; O—C(═O)—C₁₋₄-aliphatic residue; NH₂; NH(C₁₋₄-aliphatic residue); N(C₁₋₄-aliphatic residue)₂; N(H)C(═O)—C₁₋₄-aliphatic residue; S—C₁₋₈-alkyl; SCF₃; S(═O)₂C₁₋₄-aliphatic residue; S(═O)₂—N(H)C₁₋₄-aliphatic residue.

The compounds according to the invention are defined by substituents, for example by R^(A), R^(B) and R^(C) (1st generation substituents), which are themselves optionally substituted (2nd generation substituents). Depending on the definition, these substituents of the substituents can in turn themselves be substituted (3rd generation substituents). If, for example, R^(A)=aryl (1st generation substituent), aryl can itself be substituted, for example by C₁₋₄-aliphatic residue (2nd generation substituent). This yields the functional group aryl-C₁₋₄-aliphatic residue. C₁₋₄-aliphatic residue can then in turn itself be substituted, for example by Cl (3rd generation substituent). Overall, this then yields the functional group aryl-C₁₋₄-aliphatic residue-Cl.

In a preferred embodiment, however, the 3rd generation substituents cannot themselves be substituted, that is to say there are no 4th generation substituents.

In another preferred embodiment, the 2nd generation substituents cannot themselves be substituted, that is to say there are not even any 3rd generation substituents. In other words, in this embodiment, for example in the case of the general formula (I), the functional groups for R¹ to R¹⁴ can in each case optionally be substituted, but the substituents in each case cannot themselves be substituted.

In some cases, the compounds according to the invention are defined by substituents which are or carry an aryl or heteroaryl radical, in each case unsubstituted or mono- or poly-substituted, or which, together with the carbon atom(s) or heteroatom(s) joining them as ring member(s), form a ring, for example an aryl or heteroaryl, in each case unsubstituted or mono- or poly-substituted. Both these aryl or heteroaryl radicals and the aromatic ring systems so formed can optionally be fused with C₃₋₁₀-cycloaliphatic residue or heterocycloaliphatic residue, in each case saturated or unsaturated, that is to say with a C₃₋₁₀-cycloaliphatic residue such as cyclopentyl or with a heterocycloaliphatic residue such as morpholinyl, it being possible for the C₃₋₁₀-cycloaliphatic residue or heterocycloaliphatic residue radicals so fused to be unsubstituted or mono- or poly-substituted.

In some cases, the compounds according to the invention are defined by substituents which are or carry a C₃₋₁₀-heterocycloaliphatic residue or heterocycloaliphatic residue, in each case unsubstituted or mono- or poly-substituted, or which, together with the carbon atom(s) or heteroatom(s) joining them as ring member(s), form a ring, for example a C₃₋₁₀-cycloaliphatic residue or heterocycloaliphatic residue, in each case unsubstituted or mono- or poly-substituted. Both these C₃₋₁₀-cycloaliphatic or heterocycloaliphatic residue and the aliphatic ring systems formed can optionally be fused with aryl or heteroaryl, that is to say with an aryl such as phenyl or with a heteroaryl such as pyridyl, it being possible for the aryl or heteroaryl radicals so fused to be unsubstituted or mono- or poly-substituted.

Pharmacological Experiments Method I. Fluorescence Assay Using a Voltage Sensitive Dye

Human CHO—K1 cells expressing KCNQ2/3 channels are cultivated adherently at 37° C., 5% CO₂ and 95% humidity in cell culture bottles (e.g. 80 cm² TC flasks, Nunc) with DMEM-high glucose (Sigma Aldrich, D7777) including 10% FCS (PAN Biotech, e.g. 3302-P270521) or alternatively MEM Alpha Medium (lx, liquid, Invitrogen, #22571), 10% fetal calf serum (FCS) (Invitrogen, #10270-106, heat-inactivated) and the necessary selection antibiotics.

Before being sown out for the measurements, the cells are washed with a 1×DPBS buffer without Ca²⁺/Mg²⁺ (e.g. Invitrogen, #14190-094) and detached from the bottom of the culture vessel by means of Accutase (PAA Laboratories, #L11-007) (incubation with Accutase for 15 min at 37° C.). The cell count then present is determined using a CASY™ cell counter (TCC model, Scharfe System) in order subsequently to apply, depending on the density optimization for the individual cell line, 20,000-30,000 cells/well/100 μl of the described nutrient medium to 96-well measuring plates of the Corning™ CeIIBIND™ type (Flat Clear Bottom Black Polystyrene Microplates, #3340). Incubation is then carried out for one hour at room temperature, without gassing or adjusting the humidity, followed by incubation for 24 hours at 37° C., 5% CO₂ and 95% humidity.

The voltage-sensitive fluorescent dye from the Membrane Potential Assay Kit (Red™ Bulk format part R8123 for FLIPR, MDS Analytical Technologies™) is prepared by dissolving the contents of a vessel Membrane Potential Assay Kit Red Component A in 200 ml of extracellular buffer (ES buffer, 120 mM NaCl, 1 mM KCl, 10 mM HEPES, 2 mM CaCl₂, 2 mM MgCl₂, 10 mM glucose; pH 7.4). After removal of the nutrient medium, the cells are washed with 200 μl of ES buffer, then covered with a layer of 100 μl of the dye solution prepared above and incubated for 45 min at room temperature with the exclusion of light.

The fluorescence measurements are carried out with a BMG Labtech FLUOstar™, BMG Labtech NOVOstar™ or BMG Labtech POLARstar™ instrument (525 nm excitation, 560 nm emission, Bottom Read mode). After incubation of the dye, 50 μl of the test substances in the desired concentrations, or 50 μl of ES buffer for control purposes, are introduced into separate cavities of the measuring plate and incubated for 30 min at room temperature while being shielded from light. The fluorescence intensity of the dye is then measured for 5 min and the fluorescence value F₁ of each well is thus determined at a given, constant time. 15 μl of a 100 mM KCl solution (final concentration 92 mM) are then added to each well. The change in fluorescence is subsequently measured until all the relevant measured values have been obtained (mainly 5-30 min). At a given time after KCl application, a fluorescence value F₂ is determined, in this case at the time of the fluorescence peak.

For calculation, the fluorescence intensity F₂ is corrected for the fluorescence intensity F₁, and the activity (ΔF/F) of the target compound on the potassium channel is determined as follows:

${\left( \frac{F_{2} - F_{1}}{F_{1}} \right) \times 100} = {\frac{\Delta \; F}{F}(\%)}$

In order to determine whether a substance has agonistic activity,

$\frac{\Delta \; F}{F}$

can be related to

$\left( \frac{\Delta \; F}{F} \right)_{K}$

of control wells.

$\left( \frac{\Delta \; F}{F} \right)_{K}$

is determined by adding to the well only the buffer solution instead of the test substance, determining the value F_(1K) of the fluorescence intensity, adding the potassium ions as described above, and measuring a value F_(2K) of the fluorescence intensity. F_(2K) and F_(1K) are then calculated as follows:

${\left( \frac{F_{2K} - F_{1K}}{F_{1K}} \right) \times 100} = {\left( \frac{\Delta \; F}{F} \right)_{K}(\%)}$

A substance has an agonistic activity on the potassium channel if

$\frac{\Delta \; F}{F}$

is greater than

$\left( \frac{\Delta \; F}{F} \right)_{K}:{\frac{\Delta \; F}{F} > \left( \frac{\Delta \; F}{F} \right)_{K}}$

Independently of the comparison of

$\frac{\Delta \; F}{F}\mspace{14mu} {with}\mspace{14mu} \left( \frac{\Delta \; F}{F} \right)_{K}$

it is possible to conclude that a target compound has agonistic activity if

$\frac{\Delta \; F}{F}$

increases dose dependently.

Method II. Low-Intensity Tail Flick Test (Rat)

In the low-intensity tail flick test, the determination of the antinociceptive effect of the compounds according to the invention towards an acute noxious thermal stimulus is carried out by measuring the withdrawal reflex of the rat tail (tail flick) in response to a radiant heat beam (analgesia meter; model 2011 of the company Rhema Labortechnik, Hofheim, Germany) according to the method described by D'Amour and Smith (J. Pharm. Exp. Ther. 72, 74 79 (1941). To this end, the rats were placed in a plexiglas restrainer, and a low-intensity radiant heat beam (48° C.) was focused onto the dorsal surface of the tail root. The stimulus intensity was adjusted to result in a mean pre-drug control withdrawal latency of about 7 s, thus also allowing a supraspinal modulation of the spinally mediated acute nociceptive reflex. A cutoff time of 30 s was applied to avoid tissue damage. Male Sprague-Dawley rats (Janvier, Le Genest St. Isle, Frankreich) with weights of 200-250 g were used. 10 rats were used per group. Before administration of a compound according to the invention, the animals were pre-tested twice in the course of five minutes and the mean of these measurements was calculated as the pre-test mean. The antinociceptive effect was determined at 20, 40 and 60 min after peroral compound administration. The antinociceptive effect was calculated based on the increase in the tail withdrawal latency according to the following formula and is expressed as percentage of the maximum possible effect (MPE [%]):

MPE=[(T ₁ −T ₀)/(T ₂ −T ₀)]*100

In this, T_(o) is the control latency time before and T₁ the latency time after administration of the compound, T₂ is the cutoff time and MPE is the maximum possible effect. Employing variant analysis (repeated measures ANOVA) allowed testing of statistically significant differences between the compounds according to the invention and the vehicle group. The significance level was set to p≦0.05.
